It all started with a tweet about Jenner's new makeup brushes, which the 20-year-old is already under fire for, as many are saying they're priced too high. Star used this opportunity to offer his own opinion on the matter, writing, "Are the new @kyliecosmetics makeup brushes made out of animal hair? Is that why they're so expensive?? BITCH I'M STILL DUMBFOUNDED!!!!" and then quickly followed up with a second tweet, claiming that it was just "an honest question" and urged his followers to not take it for anything but that. "I'll still review it... LOL I ain't mad.. Just want to know why her team is being lazy," he added.

Then he changed topics, this time accusing the reality star of copying his packaging in a tweet he's since deleted. "I gotta know ONE THING... With all that fucking money she's made, why did @kyliecosmetics use the SAME PACKAGING as my liquid lipsticks that have been out since 2014??? Invest and make something different maybe?" Talk about shots fired.

And naturally, he didn't stop there. Though he deleted the initial tweet, he continued to respond to mentions and claimed he wasn't actually upset. "Remember when I said I wasn't mad but people are coming into my mentions acting like I am? HAHA STOP IT! I'm aware other brands have used the same component too. Doesn't change the question ;)," he wrote, referencing the fact that some followers were quick to point out that other brands (such as Sugarpill and Dose of Colors) have come out with similar packaging as well. (FYI, this is likely because there are only so many cosmetic manufacturers out there, so sometimes brands will indeed boast comparable packaging to their counterparts.)

Before signing off, Star said he would buy Kylie's products himself to review, and added that he's not worried about being on a brand's PR list. Finally, he switched gears and gave Rihanna a shoutout, thanking her for killing it and showing the industry how it's done.

Allure reached out to Star's team for comment but has not heard back. We will update this post accordingly when and if we do. In the meantime, check out the thread in full, below.
